摘要
该模式建立以"苜蓿+无芒雀麦+冰草+披碱草"为主的豆禾混播人工草地放牧肉牛(羊),实行夏秋季节划区轮牧、冬春季节舍饲的生产经营模式。通过为期4年的草地建植、管理与可持续利用技术研究与效益评价,初步总结出适用于我国北方的生态生产兼顾的草牧业创新发展模式。研究表明,该模式草地产量提高了20倍,牧草品质达到一级草水平,草地载畜量增加了10倍,家畜产出率提高40.3%,其经济、社会、生态效益显著。探索出了以家庭牧场、种养大户或牧民联户为生产经营主体,适合草原牧区种养结合,草畜平衡的可复制新型生产模式、脱贫模式。
The model established a mixed grass artificial grassland with" Medicago Sativa+ Bromus inermis + Agropyron cristatum + Elymus dahuricus", which was used to graze beef cattle(sheep). The model implemented rotational grazing in summer and autumn, and house feeding in spring and winter. Through a four-year grassland planting, management and sustainable use, the article initially summarized the innovative development model of grassland husbandry suitable for northern China. The results showed that the grassland yield increased by 20 times, the forage quality reached the first grass level, the grassland carrying capacity increased by 10 times, and the livestock production performance increased by 40.3%. Economic, social and ecological benefits of the model were significant. Exploring a new replicate type of production and poverty alleviation model that was based on family farms, large-scale breeding farms or herdsmen’s households, it was suitable for combination planting and breeding and balanced grass and livestock in pastoral areas.
